JOZSEF NAGY, OF CLEVELAND, OHIO.

CAR COUPLING AND BUIVIPER.

Specification of Letters Patent.

Patented April 20, 1909.

Application filed February 29, 1908. Serial No. 418,508.

To all whom it may concern:

Be it known that I, Jozsnr NAGY, subject of Franz Joseph, Emperor ofAustria-.Hungary, residing at Cleveland, in the county of Cuyahoga andState of Ohio, have invented certain new and useful Iinprove- 'ments inCar Couplers and Bumpers, 0t

which the followingis a specification.

This invention is a car coupler of the type in which one car has asocket with hooks therein and the other has a rod or bar with a headwhich is engaged by the hooks when it is forced into the socket as thecars come together.

The object of the invention is to form an improved coupler of the kindstated, having also improved means for releasing the coupler whendesired.

The invention is illustrated in the accompanying drawings, in which-Figure 1 is a side elevation of the coupling. Fig. 2 is a top plan viewwith the top plate of the parts removed. Fig. 3 is a top "plan view ofone of the coupler heads.

One draw head or casing is formed of upper and lower parts 1 and 2 whichwhen fitted together form a recessed head which contains the springhooks referred to. The

other drawhead is formed of upper and lower casings 3 and at whichinclose the coupling bar. These parts 1 and 2 and 8 and 4 are securedtogether by bolts or other suitable means. The coupling bar 5 projectsfrom the casing formed by the parts 3 and f and has at the outer end ahead 5 with square shoulders on opposite sides. r t its inner end it hasa cross pin 6 which moves in a slot 8 formed in each side of the casing.A coiled spring 7 bears against the cross pin at one end and against apartition 9 at the other end and acts to cushion the shock on thecoupling bar. The spring-is contained in a recess formed in the backpart of the casing. The hooks 22 are mounted in the other casingupon acentral pivot 23, said hooks having the form of levers with armsextending to the pivot referred to. 'They are arranged to engage overthe head 5 when said head is forced therebetween. A spring 20, betweenthe rear ends of the hooks, serves to close the front end of the hooksand cause them to engage over the head of the coupling bar. Locatedbetween the hooks is a block 24: with a forwardly presented concavesurface, and said block has a rearwardly extending stem 26 whichtelescopes into a tube 27 the rear end of which has a hole through whichthe pin 23 extends. A spring 25, coiled around the stem and tube tendsto advance the block and cushions the impact of the head 5 against thesame. A pin 28 extending through slots in the stem and the tube preventsaccidental separation of the parts. To open the jaws 22 a vertical shaft12 is provided, located between the rear ends of the jaws and connectedthereto by chains 19. "his shaft extends through the top of the casingand has at its upper end a beveled gear 17 which meshes with a beveledgear 16 on a cross shaft 14 which is provided at its outer end with acrank handle 15 which may be located at the side of the car so as to beaccessible to a train man without having to enter between the cars. Theupper and lower plates of the casing are strengthened, where the pin 23is held, by fillets 11 around the holes through which said pin extends.

lVhen the crank 15 is turned the gearing causes the chains to wind up onthe shaft and draws the rear ends of the hooks together, thereby openingthe same at the front and allowing the coupling bar 5 to be pulled outor disconnected. \Vhen the crank is released the spring 20 throws thehooks together in position to recngage the head of the coupling bar whenthe same is again forced thercbetween. An advantage arises from the factthat the movable parts of the coupling are inclosed or incased andconsequently are not apt to be rendered inoperative by deposits of snowor sleet thereon. It is also unnecessary for the train man or attendantto hold the coupling bar in hisv hands to enter the same between thejaws or hooks.

I claim:

A car coupling member comprising a hollow drawhead having oppositespringpressed hooks therein, a pin on which the hooks are pivoted, and aspring-supported block between the hooks and connected at its rear endto the pin and adapted to receive the impact of a head inserted betweenthe hooks.

In testimony whereof I aflix my signature, in presence of two witnesses.

JOZSEF NAGY.
